Zeolite Catalyst Advanced Materials Patent Landscape 2026
- Filing activity has cooled since its 2018 peak of 47. the midpoint year of 2022 sat at 28, and the trend has not recovered since — this is a mature claim space, not a growing one.
- Refining and petrochemical IPC codes dominate the corpus. C10G (hydrocarbon oils & refining) and C07C (acyclic/carbocyclic compounds) appear alongside the core B01J and C01B catalysis codes, showing where hierarchical zeolite claims actually get used.
- The strongest co-filing pairs are all Saudi-anchored. Saudi Arabian Oil Company (Saudi Aramco)'s partnerships with JGC Catalysts and Chemicals Ltd., King Abdullah University of Science and Technology (KAUST) and a Japan-based cooperative research centre account for the three highest co-assignee counts in the dataset.
Filing growth compares 2021 (34 records) with 2024 (23) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 342 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
The corpus tracks 342 patent families published between 2015 and the 2026 cut-off, filtered to filings that combine core zeolite/molecular-sieve terminology with hierarchical-zeolite, metal-zeolite-composite, nanozeolite or framework-modification language, and classified under B01J29, C01B39 or B01J35. That combination isolates work on pore architecture and composite structure rather than bulk zeolite synthesis or unrelated adsorption uses.
Publication for the most recent filing years lags roughly 18 months behind the actual filing date, so 2025 and 2026 counts will rise as more applications clear examination and publish. Read the recent-year drop in the trend as an artefact of that lag combined with a genuine slowdown from the 2018 peak, not as a cliff.

Filing trend and technology composition
Two views of the same 342 families: how filing volume has moved year over year, and which IPC subclasses the claims actually sit in.
A 2018 peak followed by a flat-to-declining run
Filings rose from 9 in 2017 to a peak of 47 in 2018, then settled to 28 by the 2022 midpoint. There is no second wave visible in the data through the (partial) most recent year — treat any apparent tail-off in the last one to two years as publication lag rather than a real drop.
Catalysis and refining codes carry the bulk of the volume
B01J (284 records) and C01B (198) confirm this is fundamentally a catalysis/inorganic-chemistry corpus, but C10G (94) and C07C (70) show a heavy downstream pull into hydrocarbon refining and organic synthesis. Smaller counts in C08F, A61K, B01D and C08G (11–24 each) mark adjacent uses — polymerisation, medicinal formulation, separation — that sit outside the core claim density.
Shares are the percentage of the 342 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Citation counts are pulled from within this searched corpus and skew toward older filings that have had more time to accumulate citations — treat them as a measure of influence on the field's vocabulary, not of current commercial relevance.
Patent titles are shown in the language they were filed in, not translated, so that each record stays verifiable against the original filing — a translated title will not match in Eureka or in any national register. Each row carries its publication number; clicking a row searches Eureka by that number.

Four read-outs from the filing trend, IPC spread and citation network — useful for deciding where fresh claims still have room and where they don't.
Growth has flattened, not accelerated
The 2018 peak of 47 filings has not been matched since; by 2022 the annual count had fallen to 28. Combined with near-zero momentum among the leading assignees in the most recent year, this reads as a claim space that filled up early rather than one still expanding.
Core catalysis claims outnumber refining-specific ones roughly 3:1
Most families are written as general catalyst/framework claims (B01J, C01B) rather than refining-application claims (C10G). That leaves refining-specific implementation — reactor conditions, feedstock-specific tuning — comparatively less crowded than the underlying material claims.
Chinese synthesis art anchors the citation graph
The most-cited record in the corpus is a Chinese hierarchical-pore zeolite preparation method, cited well ahead of the next entries. Newer filings citing it are building directly on pore-structuring methodology first described there rather than on later composite or doping work.
Collaboration is concentrated around one hub
All three strongest co-assignee pairs share Saudi Arabian Oil Company (Saudi Aramco) as one party, paired separately with a Japanese catalyst maker, a Saudi university and a Japan-based research cooperative. That is a hub-and-spoke pattern, not a broad collaborative network.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to zeolite catalyst advanced materials, with the prior art for and against each one.

Co-filing in this corpus is dominated by one assignee's separate bilateral partnerships rather than a shared multi-party network — worth noting before assuming any of these partners collaborate with each other directly.
Assignees and where their momentum stands
Ranking by family count is rendered separately; what matters here is the shape of activity — concentrated at the top, largely stalled in the most recent year, and thin outside a small cluster of Saudi- and Thai-linked organisations.
The top filers have gone quiet
Saudi Arabian Oil Company (Saudi Aramco), JGC Catalysts and Chemicals Ltd., Saudi Aramco Services Company and the Japan cooperative research centre all show 0 filings and -100% year-on-year in the latest tracked year. Given publication lag, some of this is filings still in the pipeline — but the pattern is consistent across nearly every leading name, not isolated to one.
Saudi Arabian Oil Company (Saudi Aramco) sits at the centre of the network
Its pairing with JGC Catalysts and Chemicals Ltd. is the single strongest co-assignee relationship in the dataset, followed closely by its separate ties to King Abdullah University of Science and Technology (KAUST) and a Japan-based petroleum research cooperative. Any competitive read of this space has to treat these three relationships as one actor's portfolio strategy, not three independent alliances.
PTT Global Chemical Public Company Limited is filing toward a specific reaction
Its hierarchical zeolite catalyst filing targets C5-C9 alkane aromatization specifically — a narrower, application-anchored claim style than the Saudi cluster's broader composite and framework claims.

In this corpus, hierarchical zeolite claims describe frameworks engineered to have more than one pore-size regime — typically combining the standard microporous zeolite structure with introduced mesopores or macropores to improve diffusion and reduce coking. Claims usually specify either a synthesis route (templated growth, post-synthetic treatment) or a resulting pore-size distribution as the point of novelty. Because this is the dominant claim style in the dataset, a new filing needs to distinguish itself on the specific pore-generation method, not just the presence of hierarchy.
The trend data shows filings rising from 9 in 2017 to 47 in 2018, then falling to 28 by 2022 with no recovery visible since. This pattern is consistent with an early land-grab on core composite and framework-modification claims, followed by later filers finding less open claim space. Recent-year figures are also understated by roughly 18 months of publication lag, so some of the apparent decline in the last year or two will correct upward as pending applications publish.
Co-assignee data points to a Saudi-anchored cluster: Saudi Arabian Oil Company (Saudi Aramco) pairs separately with JGC Catalysts and Chemicals Ltd., King Abdullah University of Science and Technology (KAUST) and a Japan-based petroleum research cooperative, and those three relationships are the strongest co-filing pairs in the dataset. Saudi Aramco Services Company and PTT Global Chemical Public Company Limited also appear among the tracked assignees. Nearly all of the leading names show zero filings and -100% year-on-year momentum in the latest tracked year, though this is partly a publication-lag effect.
The IPC composition shows heavy density in B01J (284 records) and C01B (198), with much thinner counts in adjacent codes like C08F, A61K and B01D (11–24 each). That gap suggests under-claimed combinations such as zeolite-polymer hybrid membranes, zeotype frameworks for medicinal delivery, and fine-grained nanozeolite crystallite control — areas that touch the core chemistry but haven't been claimed as densely. Any freedom-to-operate check should still start from the core B01J/C01B prior art before relying on thinner adjacent-code counts as a sign of true openness.
Citation counts in this corpus are a measure of influence within the searched set, not a live indicator of commercial importance — they mechanically favour older filings that have had more years to accumulate citations. CN103073020A leads the list by a wide margin (122 citations) largely because it's an early, foundational hierarchical-pore preparation method that later filings cite as background. Use citation rank to find the technical vocabulary a field builds on, and use recent filing and assignee-momentum data separately to judge what's currently active.
